TO ALL WHOM IT MAY CONCERN:

Be it known that I, WILLIAM M. TrLnsroN, of New York, county of NewYork,and State of New York,

have inventedcertain new and useful Improvements in Paper-Fasteners; andIdo hereby declare the following to bcafull, clear, and exactdescription of the same, reference being had to the'accempanyingdrawing, making a. part of this specitication, in whichi i Figure 1 is aperspective view of my fastener.

Figure 2 is a view of the fastener struck out before being formed up.

Figure 3 is a top plan View after being formed up.

Figure 4 is a side view of same.

Figure 5 is a sectional view of the fastener applied to use.

Similar letters of reference denote corresponding parts in all thefigures.

My invention relates to certain improvements in paper-fasteners, wherebyI am enabled te make the fastener serve as its own punch, and thus doaway with the expensive machines heretofore used for punching the holespreparatory to fastening the paper together.

To enable others skilled inthe art to make and use my invention, I willproceed to describe the same.

In making my fastener, I first strike out, vof sheet brass or othermetal, a piece, A, as shown in fig. 2, having on each end a short arm orlip, @and having on its exterior long arms, a a, punched loose on threesides, as also shown in iig. 2.

After being struck up, (or bythe same operation,)I fiuto or groov'eeachand all of the arms to render them stili'. These arms are then bent atright angles to the main body of the fastcnergvhcn it is ready for use.

4In fasteners, as heretofore constructed, one great objection has beenthat, being made of thin Aflat metal, they would not bear the strain ofbeing forced through more than a few thicknesses of paper, hence thenecessity of having a separate machine for inserting the fasteners,which is not only expensive, buta slow and tedious operation where thereare a number to be' inserted lat one time. But, in my improved fastener,the

arms or points being stii, they may he quickly and easily insertedwith-the fingers, and thc ends bent down.

As will be seen in tig. 5, the long arms are bent down after thefastener is inserted, and the short arms bent down or lapped" over them,the grooving in point a coming under that of point b, thus preventingthe points from being caught in anything and becoming unbent andloosened, as is common in others.

It is obvious that the fastener may be made of any length, and that forstrength there may be any suitable number of the intermediate arms. Itis also obvious -that my principle of iuting may be applied to any otherforms of fasteners having points to penetrate the paper. 1

Having thus described myinvention, what I claim, and desire to secure byLetters Patent, is

Corrugating, Huizing, or grooving the points and arms, for punching thcholes as` described.
